From inspecting residential wells over the past two decades, I can tell you this: most well problems start small and get expensive the longer they are ignored. The guidance below reflects what I have actually seen in real well systems, not just what the manuals say.
Your well’s casing is a buried $5,000-$30,000 investment. You can’t see cracks or corrosion from the surface, and by the time you notice symptoms — sand in your water, dropping flow, or coliform breakthrough — the damage is usually well into the casing. A well inspection camera lets you see inside and catch problems before they cost a whole new well.
When Does a Well Need a Casing Inspection?
- Sand appearing in water — casing holes or cracked screen sections
- Coliform bacteria returns — surface water entering through a breach
- Reduced capacity/drop in flow rate — internal corrosion or scale buildup
- Regular maintenance — every 5-10 years for wells over 15 years old
- After flooding or seismic events — ground movement can crack casings
- New well purchase — verify casing integrity before buying
Top Picks — Best Well Inspection Cameras Ranked
Best Overall: EVO-1000 400ft Well Camera System
Price: ~$1,800-$2,500 | Rating: ★★★★☆
Professional-grade standard. 1080p LED-lit camera head (just 1.5″ diameter) slides through 4″ and 6″ casings. Records video to USB drive. Features depth encoder (within 1/4 inch accuracy) and bright floodlight that cuts through murky water. Stainless steel construction.
Best for DIY: Borescope-WC Well Inspection Kit
Price: ~$350-$600 | Rating: ★★★★☆
Best option for homeowners who want to inspect their own well. Flexible IP68-rated boom camera connected to a WiFi-enabled monitor. View live feed on phone/tablet, snap photos of issues. 1″ wide camera head fits most standard wells. Not as sharp as pro systems but far more affordable.
Pro Choice: Well-1000 Pro Inspection Kit
Price: ~$5,000-$8,000 | Rating: ★★★★☆
Top-tier inspection system used by well drilling contractors. HD camera heads in 1″, 1.5″, and 2.5″ diameters. Pan-and-tilt mechanism inspects well floor after penetrating casing. Real-time measurement overlay. Timestamped photos for court-ready documentation.
💡 Pro Tip: If you can’t afford a professional-grade camera ($1,800+), rent one through your local agricultural extension office. Many rent the EVO-1000 for ~$150/day. A single inspection every 10 years is far cheaper than a $15,000 well replacement.
⚠️ Important: Never lower a camera into a well with known hazardous gases (hydrogen sulfide, methane, high CO2). Always check air quality first with a gas detector.

Bottom line: A well casing inspection is the single most valuable maintenance procedure for aging wells. A $500 inspection can reveal a problem that would cost $15,000 to miss. Use the Borescope-WC for annual DIY checkups and a professional EVO-1000 review every 5-10 years. If you spot corrosion or holes, fix them while the damage is still localized to a spot repair.
